- Aerodynamics is increasingly crucial in the improvement of electric vehicles’ range. At highway speed a 10% reduction in aerodynamic drag gives a 5% improvement in range. Responding to this need, Applus IDIADA presents at the Geneva International Motor Show 2018, the CRONUZ project, an EV compact SUV concept car with an optimal aerodynamic performance.The CRONUZ was developed from a blank page to fulfil best-in-class aerodynamic values thanks to the seamless cooperation between Applus IDIADA’s aerodynamicists and designers. That cooperation allowed the upper-body to be optimized while keeping the design concepts. This concept car includes breakthrough aerodynamic solutions that include active and passive aerodynamic enablers that focus on key areas such as the wheelhouses and underbody.
